Abstract
For use in multiport digital conference arrangements adapted to sum speech samples of selected speakers, the disclosed method and apparatus improves the quality of communication by holding over selected ports for varying time intervals depending on the interval of speech above a threshold. Furthermore, a minimum number of ports is always enabled to provide background noise when all the conferees are silent.
